Abstract— Countries over the world facing endemic electrical energy shortages have an added bane of power theft. Power shortages have a very detrimental effect on the overall economic growth of the country. This project has been developed as a smart meter that would make an effort to curb power theft prevailing in the distribution segment of power systems with the added benefit of detection of current overload and a notification via SMS to the main station indicating the same. Applications such as smart billing and home automation are features of this project. Overloads due to power theft detected, automate an SMS generation program that alerts concerned authorities. Consumer usage units for billing can be checked with just an SMS. Non-payment of dues by individual households may enable authorities to shut down power supply to the defaulting consumer from source. Devices can be switched ON/OFF by the user with a single SMS. Concepts of power line communication (PLC) and GSM modules along with controllers such as PIC and Arduino controllers have been used as the basis and support structure to this project.
this value to the power consumed by each consumer using power line communication concept. If any mismatch occurs in between the readings, it would indicate power theft and the transformer would send a SMS to the authorities indicating current theft is occurring at that transformer. Also, if a customer is using more power than his meter rating. Then a SMS will be sent to the authorities indicating current overload. A bill is commercial document indicating the used units of power. Normally to check the consumed units from the meter, a officer had to be sent to each house to get the consumed units. This method is very lengthy and also sometimes he may not be able to gain access to the meter. Our project can send the consumed units of the customer with help of a SMS. The authorities would have to send a SMS to the main transformer asking for consumed units of each meter connected to it. The transformer would communicate to each and every meter connected to it with the help of power line communication and then send a message to the electricity department indicating the consumed units of each user.
Keywords: smart meter, power theft, overload, smart billing, home automation, power-line communication (PLC), GSM module, PIC controller, Arduino.
In case of non-payment of any previous dues, the authorities can disconnect current getting delivered to the customer by sending a single message. Also control of any devices in the household is possible from a remote end my sending a single SMS. Thus, making it a successful home automation system as well.
1.INTRODUCTION According to the International Energy Agency (IEA), the world generates more than 66% of its electricity from fossil fuels and another 8% from nuclear energy. All of which are non-renewable. Hence there would be a time when there would be no fossil fuels left, and the world would have to go in darkness. It’s difficult to imagine the world without electricity. Therefore there is a need for legitimate use of energy. This won’t be possible as long as current theft occurs. According to The Times of India Power thefts cost India Rs 45k core in 2009-10. Hence there is a need to implement a successful power theft detection module.
At the transformer section we have used a PIC microcontroller along with a GSM module and a PLC module. We have also used a current sensor to detect the power getting delivered from the transformer. At the consumer section we have used a Arduino controller along with a few relays, PLC module and a basic power meter to calculate the consumed units. Also we have used a current sensor to detect the power consumed by the consumer. Note, only PLC modem is used to communicate between distribution transformer section and consumer section. And a single GSM unit is present at the distribution transformer section.
Our project uses a GSM module to communicate with the authorities. Normally current theft is done by direct hooking from line or by bypassing the energy meter. To detect this we continuously monitor the power that is being delivered by the main transformer and comparing
